globalfoundries announces new singapore plant

globalfoundries announces new singapore plant

The new facility will be developed in partnership with the Singapore Economic Development Board and with co-investments from committed customers, GlobalFoundries said. More than $4 billion will be invested into the development, according to the company.

"Our new facility in Singapore will support fast-growing end-markets in the automotive, 5G mobility and secure device segments with long-term customer agreements already in place," GlobalFoundries CEO Tom Caulfield said in a statement.

A virtual groundbreaking ceremony for the plant was attended by Singapore's Transport Minister S Iswaran as well as Mubadala Investment Company Managing Director and Group CEO Khaldoon Khalifa Al Mubarak, among others.

"The semiconductor industry is a key pillar of Singapore's manufacturing sector, and GlobalFoundries' new fab investment is testament to Singapore's attractiveness as a global node for advanced manufacturing and innovation," Beh Swan Gin, chairman of the Singapore Economic Development Board said in a statement.

Semiconductors are critical components that power all kinds of electronics, from smartphones to computers to the brake sensors in cars. Their production involve a complex network of firms that design the chips, companies that manufacture them as well as those that supply the technology, materials and machinery to do so.

GlobalFoundries is a so-called "pure" foundry, with factories in the U.S., Germany and Singapore. Foundries are companies that are contracted by semiconductor firms to build chips. GlobalFoundries manufactures semiconductors designed by the likes of AMD,QualcommandBroadcom.

Taiwan Semiconductor Manufacturing Company, or TSMC, is the world's biggest foundry by market share and revenue, according to TrendForce. It has about 56% market share, followed by Samsung (18%), UMC (7%) and GlobalFoundries (7%).

For his part, Caulfield told CNBC this year that GlobalFoundries is planning to invest $1.4 billion in its foundries to address the shortage. The company plans to expand capacity at all its manufacturing sites.

sand processing

sand processing

Sand Processing at RRC is accomplished by rotary attrition, heat, dust removal and manual screening. After processing, the molding and core sands are used for many different Michigan DEQ approved uses. A varity of products are produced from recycled foundry sand including asphalt, concrete, soils blends, liner cover, remediation media and fill material. Sand is RRC's main reason for existence, finding ways to responsibly reuse molding sands and saving virgin sand sources for the future are our goals.

Foundry sand is clean, uniformly sized, high quality silica sand, used in foundry casting processes. The sand is bonded to form molds or patterns used for ferrous (iron and steel) and non-ferrous (copper, aluminum, brass) metal castings. Shake-out sand from completed metal casting are often reclaimed back into the foundry sand process.

Green Sand is silica sand with minor ingredient additives such as bentonite clay, water, and sea coal. In general, the type of metal being cast determines the minor ingredient portions as well as the gradation of the sand required. The green sand is reclaimed by a thermal process that requires cooling the sand before it can be reintroduced into the casting process. The majority of foundries use green sand casting in their process method.

No bake casting is another popular method used to produce core molds or smaller volumes of complex castings for both ferrous and non-ferrous metals. This method applies a chemical binder/catalyst to the sand just before filling the mold which undergoes a chemical reaction to harden the sand and maintain the molds shape. As this reaction is sensitive to temperature, it is very important to maintain a consistent and uniform temperature of the sand to optimize the cast product quality.

The sand temperature can be influenced by variations in the way foundries dry and cool their reclaimed green sand, or store and distribute their no bake sand. As foundry sand is an integral part of the casting process, using sand that is too hot or too cold leads to reduced casting quality, with lasting negative affects along the entire production line. When the molten metal is poured into a mold with green sand that is too hot, it can result in higher scrap rates as well as more consumption of bentonite. No bake sand that is too hot or too cold creates inconsistencies in set time, and consumption of catalyst/binders.

Rotary cooling drums are the most popular technology to cool the temperature of the shakeout foundry sand. The sand is fed into one end of an inclined, rotating drum, with air entering the drum. The sand moves slowly downwards through the drum achieving cooling from direct contact with the air. Vibrating fluid bed coolers are also a popular cooling technology for foundry sands. The sand is conveyed on a vibrating and perforated deck. Pressurized air flows upwards through the deck to fluidize and cool the sand from direct contact as it is conveyed from one end to the other. However, both of these cooling technologies do not allow uniform cooling for all sand particles, require air permits, and are very inefficient in terms of process cost per ton of sand.

A more effective and efficient cooling technology is the indirect heat exchanger which can guarantee an even, stable and accurate final temperature for the sand. The foundry sand flows downwards, in a slow and controlled movement through the indirect heat exchanger, running between hollow, stainless steel plates. Cold water flows countercurrent within the plates to cool the sand to the desired end temperature by conduction. Neither water nor air comes in contact with the foundry sand. The slow, controlled, downward movement of the sand guarantees that all particles, regardless of inconsistent particle size are evenly cooled, eliminating variances in output temperatures of the foundry sand.

Foundry sand (also known as casting sand) consists primarily of clean, uniformly sized, high-quality silica sand that is bonded to form moulds for ferrous (iron and steel) and nonferrous (copper, aluminium, brass) metal castings.

The most common casting process used in the foundry industry is the sand cast system. Virtually all sand cast moulds for ferrous castings are of the green sand type. Green sand consists of high-quality silica sand, bentonite clay (as the binder), water and coal (a carbonaceous mould additive to improve casting finish).

The type of metal being cast determines which additives and what gradation of sand is used. The production of foundry sand requires specialist screening and classification systems and involves detailed analysis of feed material and sand grade specifications.

The recycling of non-hazardous, spent foundry sand can save energy, reduce the need to mine virgin materials and may reduce costs for both producers and end users of foundry sand. Recycled foundry sand typically finds use in construction applications but can also be used in the following ways:

An individual analysis of the spent foundry sand in terms of physical and chemical properties is required in order to determine the potential for recycling of foundry sand and its suitable applications.
